Andrew Howell, Curtis McCully, Megan Newsome, Estefania Padilla Gonzalez, Craig Pellegrino, Giacomo TerreranGlobal SN ProjectSN Ia-91T-like0.0141Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to 91T-like SNe Ia more than a week before maximum light, including SN 1995bd 10 days after peak. The supernova is closest to LCRS B125036.2-060655 (z = 0.014100, 20032dF...C...0000C, value from NED). Adopting this redshift we measure a Si II 6355 velocity of approximately 11,000 km/s. Adopting the distance modulus computed from this redshift (34.0), the g-band absolute magnitude of the object roughly coeval with the spectrum is -18.2 (apparent magnitude 15.8, from ZTF). This absolute magnitude and velocity is consistent with a rising SN Ia.2022TNSCR1120....1B
